Induction heating coil manufacturing method

Induction hardened ring production is a very professional field, especially to understand the distribution of heating layers of rectangular copper tubes. Different coppers have different requirements on their quality. Generally, a new product wants to achieve induction hardening, which is very complicated. Steps of the.



     Induction heating coil introduction


     Induction heating coils are also called inductors, electromagnetic transducers, and the like. It is an energy output device for induction heating equipment such as high frequency machines and intermediate frequency machines. In order to ensure the heating speed and efficiency, the parameters such as the number of turns (turns), diameter, shape, size, etc. must meet the requirements of impedance matching conditions and workpiece processes. Relatively speaking, the larger the diameter of the induction coil, the fewer the number of turns; the smaller the diameter, the more the number of turns.
      Commonly used sensors include external surface heating sensor, internal hole heating sensor, planar heating sensor, universal heating sensor, special heating sensor, single heating sensor, composite heating sensor, melting furnace, etc. Wait.
      In the selection of materials, small high-purity copper with resistivity should be used. The specification and wall thickness should meet the requirements of maximum working current. In order to avoid the ignition of the induction ring and the workpiece, the induction coil is ignited, and the anti-magnetic saturation causes damage and influence on the machine or the workpiece. In the production, not only must design the sensing scheme, determine the shape of the induction coil, and calculate the main parameters. Also need to choose materials such as insulation, insulation, insulation and protection. Such as high temperature insulation casing, high temperature insulation cotton, quartz tube, graphite tube, silica gel and refractory materials.

      The performance of the coil of the medium and high frequency induction heating equipment directly affects the effective output power, working efficiency, stability reliability and service life of the equipment. Therefore, each sensor should be strictly designed and manufactured, and even require experimental demonstration.

Induction heating coil manufacturing method
Since induction heat treatment is a very specialized field, there are few induction quenching heat treatment processes and insufficient standardization of induction hardening coils. Therefore, the degree of specialization of induction coil production is very low. Most users can only use the common copper plates (tubes) in the market when they manufacture the induction coils themselves, and these materials often cannot meet the needs of sensor manufacturing. For example, a rectangular copper tube, the rounded corners are too large to affect the distribution of the heating layer. In addition, the different functions of the various parts of the induction hardening coil have different quality requirements for copper. Nowadays, the series of profiles specially produced for the manufacture of sensors can be selected from the sensor companion series. In addition, the insulating parts, fasteners and cleaning materials suitable for the inductors are currently selected in the sensor companion series, which greatly improves the geometric precision of the self-made inductors and improves the stability of the process execution.
 


Benefits to users with this approach

A new product to achieve reliable induction hardening requires very cumbersome steps and requires a lot of time and effort to design and manufacture the inductor and process.

First of all, the design of the quenching sensor (mainly the working coil) needs to be repeatedly modified in combination with the equipment capability and the designer's technical reserve, and then put into a complicated manufacturing process; after the manufacturing, the actual heating and debugging is required, and the chip verification is repeated to finally determine the sensor. The geometry and a complete process, and this process requires a series of assurance measures to achieve. Sensor companion is a guarantee for process reproducibility. Otherwise, whether it is sensor replacement or sensor re-production, all process development processes are lost, the same work must be done again, or by experience, back to the old road where only the master can do good products. . The use of sensor companion can guarantee the process, no worries about quality fluctuations, even if the "master" is absent, it can produce the same quality products, greatly improving production efficiency and reducing production costs.
